To create a model in minecraft, you need to know the proper Java code. Basically, you say "Draw a Rectangle that is This big! Put it here! draw another rectangle that is this big! put it there! when my model guy runs, move it to here! and when he does this, put it here!"Over and over and over...Modeling in Minecraft is nowhere near as easy as in Battlefront. Most people re-use the human model, and just add a new texture to it, which is way, way easier.
